2种植物抗逆剂对苗木抗旱促长作用研究
Promotion Effects of Two Plant Anti-adversity Agents on Seedling Growth

纳米型植物抗逆剂（NPA）是西北农林科技大学鼠害治理研究中心研制的无公害多功能植物保健剂，集抗旱、保水、促长和预防鼠（兔）害功能于一体。为了研究NPA对苗木作用的效果，以多效抗旱驱鼠剂（RPA）为参照，采用模拟蘸浆造林方法，比较了2种药剂对油松和侧柏抗旱促长作用差异。结果显示，用150倍NPA和RPA水溶液兑成泥浆对苗木抗旱均有较好的促进作用。NPA对苗木保存率、苗高、地径和根长的促进作用大于RPA，且在低水分组和油松上表现尤为明显。
The nano-type plant anti-adversity agent (NPA), which was developed by the Research Center of Rodent Pest Management of Northwest A&F University, is the multi-functional plant health care product with pollution-free and rodent repellent, it integrates the functions of fighting drought, water retention, promoting growth and preventive rodent. In order to study the effect of NPA to seedlings, we used the RPA as the reference, and adopted simulated afforestation method of dipping the seedling roots with the slurries mixed with the reagents, drought fighting and growth promoting of two repellents to Pinus tabulaeformis and Platycladus orientalis were examined. Experimental results showed that slurries prepared by 150 times diluted NPA and RPA exhibited good promotion effects on seedlings. The promoting effect of NPA to seedling survival rate, seedling height, ground diameter and root length were higher than those of RPA, and especially in the treatments of low moisture and P. tabulaeformis seedlings
